Jacob Elordi and Kendall Jenner go incognito in Brisbane

Jacob Elordi and Kendall Jenner did their best to fly under the radar as they made their way through Brisbane Airport over the weekend.

The loved-up couple covered up from head to toe in an apparent bid to avoid attention while travelling through the domestic terminal after spending several days together in Byron Bay to celebrate the Saltburn star's 29th birthday.

But despite the baseball caps, hoodies, sunglasses, face masks and oversized scarves concealing almost every inch of their faces, there was one unmistakable giveaway that they weren't your average travellers.

The pair were weighed down by a collection of luxury designer bags from Bottega Veneta, The Row and Gucci, worth an estimated $30,000+, making it impossible to blend in with fellow passengers. 

Jacob, 29, carried an oversized black woven Bottega Veneta tote, worth $15,500, slung over one shoulder, along with a large taupe Gucci duffle bag, which retails for $6,000.

The Euphoria actor rugged up in a navy hoodie with the hood pulled tightly over his head, loose matching trackpants, white sneakers, dark sunglasses and a green face mask.

He completed the look with a patterned black and cream scarf wrapped around his neck. 

Kendall, 30, also opted for maximum disguise, hiding beneath a navy Adidas baseball cap, a black face mask and oversized black scarf wrapped high across her face.

The supermodel wore a beige oversized trench coat over loose black trousers and black shoes while carrying a striking oversized green leather handbag from The Row worth about $5,000.

Despite their attempts to remain anonymous, the pair were seen sweetly holding hands as they walked through the terminal together.

At one point, Jacob gently placed an arm behind Kendall as they navigated through the airport before continuing towards their departure gate.

The sighting comes just days after the couple were spotted enjoying an early morning stroll through Byron Bay with Jacob's beloved golden retriever, Layla.

They were photographed just before 7am, rugged up against the morning chill in matching blue and yellow winter jackets as they walked through the coastal town before stopping for breakfast at The Byron Bay General Store.

Kendall is believed to have travelled to Australia to celebrate Jacob's 29th birthday with his family and close friends.

The model arrived in the country earlier this month and has been spending time at Jacob's secluded rainforest estate near Byron Bay.

The romance appears to be going from strength to strength, with insiders recently claiming the relationship has become increasingly serious.

'They're just in that phase where they want to do everything together and things have gotten pretty serious,' a source recently told Page Six.

Jacob and Kendall were recently spotted holidaying together in Japan, where they visited the famed Tokyo restaurant Seirinkan before also stopping by popular noodle venue Udon Shin.

Although they have moved in the same celebrity circles for years, romance rumours didn't begin swirling until earlier this year.

They were first linked after being seen sharing a kiss at Justin Bieber's Coachella afterparty.

Since then, they have been photographed together in Hawaii, Montecito and across Los Angeles.

In April, the Daily Mail revealed the pair had quietly started dating months earlier.

'They were an item as far back as early February, so it's been a while,' a source said at the time.

'It helps that they have both been in Los Angeles a lot for the past couple of months. It has really given them time to bond.'
